JAMES A. BALL, OF THORNTOWN, INDIANA.

HAY-STACKER.

fiPlE-CIPTCATION forming part of Letters Patent No. 315,109, dated April '7, 1885 Application filed February 16, 1885.

To all whom it may concern.-

Be it known that I, J AMES A. BALL, a citizen of the United States, residing at Thorntown, in the county of Boone and State of Indiana, have invented a new and useful Improvement in Hay-Staokers, of which the following is a specification.

My invention relates to an improved device for loading and stacking hay.

The objects of my improvements are, first, to raise the hay by means of a short lever, and to afterward extend said lever, with its load, over the stack; second, to provide means for quickly folding the machine into compact form for moving from place to place.

The accompanying drawings illustrate my invention.

Figure 1 is a view in perspective of the complete stacker. Fig. 2 is a plan as seen from the line 2, Fig. 1. Fig. 3 is a partial section at the line 3, Fig. 2. Fig. 4 is a transverse section at 4. Fig. 5 is a similar section at 5, looking toward the end of the boom.

A is a rectangular bed-frame, two sides of which form runners to facilitate its being drawn over a field; or it may be mounted on wheels. On the central cross-timber of the bed-frame is erected a mast, B, which has a base-plate, b, which is hinged at c to the crosstimber. A collar, d, is secured to the mast, and the mast is braced by stay-rods e, which are hinged to the four corners of the frame A and hook into suitable eyes formed in said collar, the purpose being to permit the folding down of the mast upon the bed-frame.

Resting upon collar (1 is a loosely-fitting sleeve, 0, having at its lower end, on opposite sides clevisesf and g. An extensible boom is pivoted to clevis f. Said boom is made, principally, of iron tubing, and consists of a pair of side bars, h h, connected at the ends by suitable castings, so as to leave aspace between the bars and a central bar, i, adapted to slide longitudinally between and upon said side bars. A cross-head, j, is attached to the inner end of bar 2', having friction-rollers 7c, which engage the under side of bars h h. Bar 2' rests upon a friction-roller, Z, mounted in the casting connecting the outer ends of bars h. A bell-crank hook, on, is pivoted to the crosshead j. Said hook engages a rod, a, secured (No model.

in the side bars, h, and is released by the operator pulling on a line, 0, attached to the opposite end of the hook. The hoisting-rope p is attached to cross-heady, and passes from thence outward over a pulley, r, which is attached to the outer end of the side bars. The rope then passes upward over a pulley, s, suspended from the swivel'head t,.and downward to a snatch-block, a.

Pivoted to the upper end of sleeve 0 is a The operation of my machine is as follows:

A hay-fork or other means for holding a mass of hay is attached to the outer end of bar i and loaded with hay. Power being applied to the hoisting-rope, hard is prevented from drawing outward by hook an engaging rod n, and the free end of the boom is consequently raised. with its load, until a suflicient height has been attained, the load being lifted with comparative case, because of the shortness of the boom. Bar 4) is now drawn forward into engagement with rod n, thereby holding the boom against further upward or downward movement. The load being balanced by the counterpoise 'w, the boom, with its load, is easily rotated about the mast to bring the load opposite any desired point. Hook m is now released from its engagement with bar n, and a further draft on the hoisting-rope slides bar i outward until the load is over the stack or other place where it is desired to deposit it. The load having been discharged, arelaxation of the draft-rope allows bar t to slide inward, the boom being held up meanwhile by ratchet-bar 2) until said bar is struck by the cross-head j, thereby disengaging it from rod n and permitting the descent of the boom.

To prepare the machine for removal, counterpoise w is removed, the boom and the counterpoise-spar are drawn up close to the mast, and stay-rods c are disengaged. The mast is then folded down upon the bed-frame.

As an additional security to the mast when raised, a bolt, q, may be passed through lugs secured to the bed-frame and across the free end of baseplate Z).

I claim as my invention 1. The combination, in a hay-stacker, of a bed-frame, amast erected upon the bed-frame, a sleeve-adapted to rotate about said mast, a boom consisting of a fixed part hinged to said sleeve, and an extensible part adapted to slide along said fixed part, a pulley secured to the free end of said fixed part, a second pulley mounted upon the mast-head, a draft-rope secured to the inner end of the extensible part of the boom and passing over said pulleys, and means for detachably connecting the extensible part of the boom with the fixed part, whereby the boom is first raised by the draft-rope and afterward extended thereby, substantiat 1y as specified.

2. In a hay-stacker, the extensible boom consisting of a fixed part composed of two parallel bars united at their ends and having a space between them, a third bar arranged to slide between said parallel bars and having a cross-head engaging said bars, and a hook pivoted to said sliding part and adapted to engage said fixed part, all combined substan tially as and for the purpose specified.

3. In a hay-stacker, the combination of a bed-frame, a mast erected on said frame, a sleeve adapted to rotate about the mast, an extensible boom hinged to the sleeve, a spar hinged also to the sleeve opposite the boom, a counterpoise-Weightattached to said spar, and ropes and pulleys for raising said boom and spar, all substantially as specified.

4:. The combination, with the mast, the sleeve thereon, and the boom hinged to said sleeve, of the ratchet-bar pivoted to the sleeve and adapted to engage the boom, substantially as and for the purpose specified.

5. The combination, in a hay-stacker, of the bed-frame, the mast hinged thereto, the collar secured to the mast, the stay-rods attached to the corners of said bed-frame and detachably connected with the collar, the sleeve adapted to rotate on the mast, and a boom hinged to said sleeve, all substantially as and for the purpose specified.
